IMPROVEMENT IN HOSE-COUPLING-S.

The vSchedule referred to in these Letters Patent and making part of the same. v

To all lwhom tt may concern Be it known that I, GEORGE SEWELL, of Brooklyn, in the county of" Kings, and State of N ew York, have made a new and useful Hose-Coupling; and I hereby declare the following to be a full and exact description of the same, reference being had' to the accompanying drawings, forming part of this specification, in which- Figures l and 2 represent the two parts which make a coupling according to my invention, these parts being exact duplicates the one ot' the other.

Figure 3 is a longitudinal section of the parts united, and shows the relative positions ofthe several portions. l

Figure 4 is a perspective view of my coupling, the parts being joined an'd locked.

Hose-couplings, as ordinarily constructed, are made so that the part. on one end of the coupling isV the counterpartv ot'- that on the other, that is, as commonly expressed, thc coupling is made up of male and female partsivhich are fastened to opposite ends of each length othose. p

This involves a serious inconvenience, sometimes, in joining pieces of hose, since it is-necessary to bring the proper ends together, so as to couple.

l My, invention obviates this diliiculty, sinceboth parts of my couplings are exact duplicates 4the one of the other, as shown in figs. l and 2.

Couplings have been made with both male and female flanges on each endso asto-interlock with each other, and couple by being turned; but this is not practical or useful, for the reason that, to join the parts,one or both lmust be turned, which twists the hose.'

My coupling dilers from this in construction, since the parts have only to be placed together, and thenlocked, by turning a collar on each piece, the 4collar carrying cam-flanges or .inclined planes, which engage into grooves on the opposite part, or mate of the coupling, sofas tocompletely lock the parts together, and

,Inns join orconple twoA or more lengths ot' hose.`

The following description will enable any one skilled in the art to which it relates to make and use my invention.

1n the drawings, .the same letter represents like I scribed.'

B B are flanged segmental lugs, each occupying one-fourth part ofthe circumference.

Ontheinside of each 4of these projecting lugs are grooves b b, tting part A, and immediately behind B B is a collar, C, attached by means of a smallrpin, m,

inserted in the part, but so that the collar can turn on the part A. 'y

The collar C is permitted to turn upon the part A by forming a recess or slot on the inside of the collar, as shown at n.

The collar C has on its front side, next to B B, two

cam-Hanges or inclined planes, o c, occupying one-` fonrth part of the circumference of the collar.

The iian ges are placed exactly opposite to each other on the collar, and when the parts are separated, the ianges c c are directly behind the lugs B B. l

In figs. 1" and 2, the collars are slightly turned, so as to bring the iauges o o partly across the space between the oppositelugs B B.

vEach collar has cuit-s own periphery cross-grooves g g,-so as to be grasped and turned by a Wrench or tongs, in coupling or uncoupling the hose.

The following is the mode oi joining the couplings:

The two parts are brought together, so. that the parts B B of tig. 1 pass between the parts B B of fig. 2, as seen in fig. 4.

The collars C O are then turned iu opposite directions, so that the cam-flanges o c of the collar, on the right-hand side, enter the grooves b b of the partB B, Y on the left-hand side, and the cam-ilanges o c of the left-hand side enter the grooves b b on the part B B, on the right-hand side.

A reverse movement of the collars will unlock and release the coupling.

In locking, it is best to turn both collars, but turnf ving either will answer. To makethe joint between the coupling perfectly tight, a rubber packing may be inserted in the usual manner on the shoulders which join; but if the parts are accurately tted, they are clamped so closely by the four cam-anges c c c o in the grooves l1 b 11 b, that the joint is suiiciently tight, without the use of packing.

I have shown two segmental lugs B B, each occupying one fourth of the circumference, but the same general mode of construction may be used by dividing the circumference-into six, eight, or any even number 4 having-cam-tlanges or inclined planesol o, so as to op# crate as described.

2. A hose-coupling, composed of' two parts, duplicates the' one of the other, in combination with locking cams or inclined planes, substantially as herein set forth.

GEO. SEWELL.
